GEORGE E. HEIDBREDER, OF QUINCY, ILLINOIS.

COMBINATION GAS AND GOAL RANGE.

Application filed October 28, 1915.

To all whom it may concern:

Be it known that I, GEORGE E. HEIDBREDER, a citizen of the United States, residing at Quincy, in the county of Adams, 'State of Illinois, have invented a new and useful Combination Gas and Coal Range; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved combination gas and coal range, and particularly to a type, known as a sheet flue range, and which is essentially different from the construction of flue shown and described in G. E. Heidbreders application filed July 20, 1915, Serial No. 40,913, which has matured into patent-of Oct. 19, 1915, No. 1,156,999. For instance, instead of two flues on one end of the oven, the present construction embodies what is known as a sheet this. In other words, one large single flue is arranged upon one end of the oven, through which the products of combustion pass. The products of combustion pass through a bottom flue under the bottom sheet of the oven, and are then baffled outwardly a through the outlet flue; or which may be closed, to direct the products of combustion downwardly through the sheet flue, under the oven, and then pass out through the outlet flue.

Another feature of the invention is the provision of a gas burner space L-shaped in plan view extending across the front portion of the top of the oven, and from the front toward the rear, at the right hand end of the range, there being a partition wall dividing the space into two partsaa forward part over the oven, and a right hand part which extends from the front to therear of the range.

One of the features of this gas burner Specification of Letters Patent.

Serial No. 53,395.

space is the provision of openings in the partition and the right hand wall of the right hand space which extends from the front toward the rear, so that the burner space may receive an L-shaped drip pan under the burners in said space, to catch the drippings, and which pan may be easily and readily removed.

Another feature is that the forward part of the partition constitutes means to support the forward rail of the top of the range, to reinforce the rail.

Another feature of the invention is the provision of a damper controlled opening in the partition, to permit the products of combustion from the burners in the two parts of the L-shaped burner space, pass downwardly through the sheet flue, or across the top of the oven to and through the damper controlled opening in the rear wall of the flue on the top of the oven so as to pass out through the outlet flue. The partition is provided with an opening, in order to afford communication between the two parts of the L-shaped burner space. The products of combustion pass from the burner space down through the sheet flue as aforesaid, especially owing to the L-shaped space being covered, as shown in the drawings.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a view in perspective of the improved combination coal and gas range constructed in accordance with the invention. Fig. 2 is a top plan view, showing the parts of the top broken away, to disclose the dampers in section. Fig. 3 is a sectional view on line 33 of Fig. 1. Fig. 4c is a sectional view on line 4P4 of Fig. Fig. 5 is a sectional view on line 5-5 of Fig. 4. Fig. 6 is a detail view of the drip pan. Figs. 7 and 8 are detail perspective views of the two sections 21 and 25 of the drip pan in Fig. 6, showing the sections separate.

Referring more especially to the drawings, 1 designates the casing of the combined coal and gas range having a fire box 2 and an ash pit 3, and leading-from the fire box is a flue 4 extending transversely across the rear upper part of the oven. and merging into what is known as a downwardly extending sheet fine 5 between the entire surfaces of the end of the sheet 6 and the end sheet 7 of the range. The sheet flue 5 extends between the bottom sheet 8 of the oven and the bottom sheet 9 of the casing of the range, thereby providing a bottom sheet flue 10, which communicates with the vertical flue 11 at the rear of the back sheet 12 01 the oven, and which flue 11 is designed to communicate with the usual outlet fine (not shown), adapted to be connected at 13 to the upper part of the flue 11. This flue 11 as will be seen is in the rear of the oven 14, but, however, is not of a width equal to the entire width of the oven, therefore the back sheet of the oven is only partially heated, that is, in comparison with the heat upon the end sheet and bottom sheet flues.

The flue 4 and the fire box 2, in plan view appears L-shaped. A pair of gas burner spaces 15 and 16 are provided, which spaces have a partition wall 17 between them, which wall is provided with openings 18 and 19, so that the two spaces are in communication, thereby forming practically an L-shaped space, which is divided from the flue 4 in the fire box 2 by the angular wall 20. The burner space 16 has its wall 21 provided with an elongated opening 22, and through which opening the drip pan 23 is inserted. This drip pan as will be seen in Fig. 6 is L-shaped in plan view, the part 24 of which is designed to fit the space 15, while the part 25 of which fits the space 16,

and when inserting this drip pan, the part 24 extends through the opening 18 of the partition wall 17. To remove the drip pan (which catches the drippings and the like), it is withdrawn from the opening 22 of the wall 21 of the space 16. The forward part or end of the partition wall 17 is formed with a notch or recess 26, to receive and sup port the forward rail 27 of the top sheet of the range, thereby reinforcing and strengthening said rail. The rear part 28 of the partition wall has an opening 29,

which may be closed or opened, as the case may be, by the damper 30, which is guided upon the pin 31, and which has openings to cooperate with the opening 29 This damper 30 has a rod 32 connected to it as at 33, and which rod is guided in the forward rail 27 of the top of the casing. The sections or parts 24 and 25 of the drip pan may be made separately, as shown in Figs. 7 and 8, and are insertible in place from the same side as the drip pan in Fig. 6 is inserted. By grasping the angled end 34 of the rod 32, the damper may be moved in one direc tion or the other, and when moved in one direction the opening 35 of the damper registers with the opening 29, while the rear end of the damper uncovers the opening 29, thereby permitting the products of combustion from the gas burner spaces 15 and 16 to pass through the openings 35, 29 and 29, to pass either downwardly through the sheet flue 5, or across the top of the oven through the flue 4, and pass out through the outlet flue, which is designed to be connected to the flue 11, by way of the opening 37, that is, when the damper 38 is open. The damper 38 is mounted in the guides 89 and 40, and is provided with a lug upon its rear face. Connected to the lug 41 of the damper 38 is a rod 42, which passes through one of the side walls of the flue 11, and terminates in an upwardly extending arm 43, which is mounted in a guide slot 44, and terminate in a knob or button 45, whereby the rod may be moved in one direction or the other, to open or close the damper 38. When the damper 38 is open, likewise the damper 30, and a. coal fire is burning in the fire box at the same time the burners 46 and 47 are I being used, the products of combustion from the fire box and the burner spaces 15 and 16 will pass directly out through the opening 3'? into the outlet flue (not shown). If only the burners are being used, then the products of combustion therefrom may either p ss directly across the top of the oven, out through the opening 37 or, if the damper 38 is closed, may pass downwardly through the sheet flue 5, and then through the bottom sheet flue 10. If only a fire is employed in the fire box, the products of combustion may pass either directly across th top of the oven and out through the opening 37, or through the flue 4, and through the sheet flue 5, under the even through the flue 10, and then pass upwardly through the rear flue 11.

The products of combustion in passing through the flue 10, it will be noted, are thoroughly baffled by the battle plate 49 (which extends angularly from the rear sheet of the oven, substantially just where the right hand side of the flue 11 is con nected to the back sheet of the oven), so that the products of combustion will circulate through the entire space or flue 10, in order to thoroughly heat the bottom sheet of the oven. In order-to afford a thorough heating of the entire bottom sheet of the oven, it is to be noted that the baffle plate 49 extends almost angularly across the bottom sheet flue 10. It is to be observed that by the manipulation of the dampers 30 and 38, the products of combustion either. from the burner spaces 15 and 16, or from the fire box may be directed to the outlet flue (not shown), either by a short and direct passage, or through a long passage. It is to be noted that the spaces 15 and 16 are covered, the same as the flue 4 and the fire box 2, and which covering 50 and 51 are provided with the usual lid closed openings 52 and 53, which enables pots and pans and the like to be'supported over the fire box or above the flue 4:, or directly above the several burners in the spaces 15 and 16.'

The invention havingbeen set forth, what it claimed as new and useful is:

1. In a combination coal and gas range, the combination of a fire box and a flue leading therefrom at the back of the range above the oven, which flue and the fire box in plan view are Lshaped, an. L-shaped gas burner space extending across the forward top portion of the oven and from the front toward the rear at the end opposite the fire box, a sheet flue at one end of the range between the end sheets of the range and oven casings and in communication with the upper flue leading from the fire box, which sheet flue extends between the bottom sheets of the range and oven casings forming a bottom flue, and terminates in a narrow flue at the rear central portion of the rear sheet of the oven, a partition between the rear portion of the end part of the gas burner space and the flue leading from the fire box across the oven, an opening in said partition, a damper to cooperate with said opening to control communication between the gas burner space and the flue across the top of the oven and the sheet flue, and a baflle plate connected to one side of the back flue adjacent where the bottom flue communicates with the back flue and extending transversely over half the width of the bottom flue and on an angle toward the ash pit of the range.

2. In a combination coal and gas range, the combination of a fire box and a flue leading therefrom at the back of the range above the oven, which flue and the fire box in plan view are L-shaped, an L-shaped gas burner space extending across the forward top portion of the oven and from the front toward V the rear at the end opposite the fire box, a

sheet flue at one end of the range between the end sheets of the range and oven casings and in communication with the upper flue leading from the fire box, which sheet flue extends between the bottom sheets of the range and oven casings forming a bottom flue, and terminates in a narrow back flue at the rear central portion of the rear sheet of the oven, a partition between the rear portion of the end part of the gas burner space and the flue leading from the fire box across the oven an opening in said partition, a damper to cooperate with said opening to control communication between the gas burner space and the flue across the top of the oven and the sheet flue, the back wall of the flue across the oven having an opening forming communication between the flue across the top of the oven and the flue at the back of the oven, and a damper to control the communication between the flue at the top of the oven and the flue at the back of the oven, so that the products of combustion either from the fire box or the gas burner space may pass either directly toward the top of the oven into the back flue, or down through the sheet flue and under the oven, and a baflie plate connected to one side of the back flue adjacent where the bottom flue communicates with the back flue and extending transversely over half the width of the bottom flue and on an angle toward the ash pit of the range.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
